I pulled my 76 2.0 stock fuel injection engine a few months back so that I could plug up some oil leaks. Other than the leaks, the engine was running O.K. Well, as O.K. as I could tell after a couple of weeks of owning my first 914. I put the engine back in just a couple weekends ago and have slowly been trying to get her going again. For a couple of days I could only get her to spin with the starter, but I wasn't getting any fuel.....I figured out today that I hadn't connected the wiring harness to the distributor. Now that I have it connected I cranked her over and I am now firing on just the #3 cylinder. I also don't smell and raw fuel coming out of the exhaust. And when I open the throttle, she seems to power up a little bit, but not much.
major points 76 2.0L D-Jet rebuilt/cleaned injectors from cruzin performance new large and small injector rubber new vacc. hoses all around just had it tuned up before I needed to pull the engine and I didn't screw with the ignition system at all. I hear no clicking when I move the throttle switch (thought I was supposed to hear the injectors clicking) If there are any other bits of info that will help in the trouble shooting process please let me know.

Otay! I got the 6 wires connected to the male connector on the top of the engine just below the #3 intake runner. I also checked the injector wires be pulling each in turn and testing them with the engine cranking. I get voltage movement with each of them, but the front driver side wires were fluctuating at a higher voltage than the others. And still, even though I am just running on the #3 cylinder she is running stronger now that I have grounded the wires on the case.
Just thinking, #3 is the first cylinder to get fuel. If my pressuer is just low enough, would the firing of the #3 cylinder be enough of a pressure drop to give too low of a fuel pressure for the rest of the injectors? |
